Here is a photo of a Greek sculpture of an ancient Celtic warrior committing suicide rather than surrendering to a Greek army. It is over 2000 years old. It shows what a beautiful physique these men had. The only physical training they did was practicing fighting. So this muscle development is all genetics. It is an accurate sculpture, because this is how the ancient Romans described them in 500BC. They said they were large in stature, impressive physiques with blond hair, fierce blue eyes and lily white skin. This is almost like a 2000 year old photograph of these magnificent people. They are gone now, they did not survive.
